About Hex to Decimal
This tool reads hexadecimal numbers and rewrites them in everyday base 10. It is useful whenever you have a hex value from code or a color and want the plain decimal number.
Frequently Asked Questions
Do I need the 0x prefix?
No. Just enter the hex digits. Upper and lower case both work, and you can convert several numbers at once with spaces.
Is there a limit on the size of the number?
No practical limit. Conversions use big integer math, so even very large numbers convert exactly. Separate multiple numbers with spaces.
